Answer:

The answer is 53 or Square Root (sqrt) of 2809

Step-by-step explanation:

a^2+b^2=c^2

28^2+45^2=c^2

784+2025=c^2

c^2=sqrt 2809

c = 53

The hypotenuse of the right triangle is h = 53 m

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of base of triangle BC = 45 m

The height of the triangle AB = 28 m

And , For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

On simplifying , we get

AC² = AB² + BC²

AC² = 28² + 45²

AC² = 784 + 2025

AC² = 2809

Taking square roots on both sides , we get

The measure of hypotenuse AC = √2809 = 53 m

Hence , the measure of hypotenuse is 53 m

Step-by-step explanation:

Answer:

1/16

Step-by-step explanation:

Given:

Given that the base of the triangle is 4 cm.

The height of the triangle is 3 cm.

The height of the prism is 8 cm.

The other side of the triangle is 5 cm.

We need to determine the surface area of the triangular prism.

Surface area of the triangular prism:

The surface area of the triangular prism can be determined using the formula,

[tex]SA=bh+(s_1+s_2+s_3)H[/tex]

where b is the base of the triangle,

h is the height of the triangle,

s₁, s₂, s₃ are the side lengths of the triangle and

H is the height of the prism.

Substituting b = 4, h = 3, s₁ = 4, s₂ = 3, s₃ = 5 and H = 8, we get;

[tex]SA=(4)(3)+(4+3+5)(8)[/tex]

[tex]SA=12+(12)(8)[/tex]

[tex]SA=12+96[/tex]

[tex]SA=108 \ cm^2[/tex]

Thus, the surface area of the triangular prism is 108 square cm.

Step-by-step explanation:

9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.

Step-by-step explanation:

The given is,

                Type A is 10 feet tall and grows at a rate of 21 inches per year

                Type B is 7 feet tall and grows at a rate of 25 inches per year

Step:1

             Convert the rate of grows of tree inch to feet,

             For Tree A,

                   Rate of grow, A = 21 inches per year

                                              = 21 × 0.0833333      ( 1 inch = 0.0833333 feet)

                                             = 1.75 feet per year

              For Tree B,

                   Rate of grow, B = 25 inches per year

                                              = 25 × 0.0833333     ( 1 inch = 0.0833333 feet)

                                             = 2.08333 feet per year

Step:2

           Difference in the tall of  Tree A & B,

                                               = 10 - 7

                                              = 3 feet

           Difference in the rate of grow of tree A & B,

                                                = 2.08333 - 1.75

                                               = 0.3333325 feet per year

Step:3

           Year take to both trees are same height,

                                               [tex]= \frac{Difference in the height of tree A & B}{Difference in the rate of grows of A & B}[/tex]

                                               [tex]= \frac{3}{0.3333325}[/tex]

                                               [tex]= 9.00[/tex]

                                               = 9 years

Step:4

            Check for solution,

            Height of tree = Height of Tree + (Rate of grow × Years)

            For A,

                                    = 10 + ( 1.75 × 9 )

                                   = 25.75 feet.........................................(1)

            For B,

                                   = 7 + ( 2.08333 × 9 )

                                    = 25.74999

                                   ≅ 25.75 feet.....................................(2)

          From Equation (1) and (2),

                  25.75 feet = 25.75 feet

Result:

          9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.

Answer:

g[f(x)] = -2(3 - x) = -6 + 2x

Step-by-step explanation:

When we substitute the function f(x) for x in g(x) = -2x, we get the composition g[f(x)]:

g[f(x)] = -2(3 - x) = -6 + 2x

Final answer:

To find g[f(x)], we substitute (3 - x) from f(x) into g(x). The solution to g[f(x)] is -6 + 2x.

Explanation:

The question asks us to find the composition of the functions f(x) and g(x), specifically g[f(x)]. To do this, we first evaluate f(x) and then use that result as the input for g(x).

Given that f(x) = 3 - x, we substitute x in g(x) for the entire function f(x).

g(f(x)) = g(3 - x) since g(x) = -2x.

Now we replace the x in g(x) with (3 - x): g(3 - x) = -2(3 - x).

This simplifies to g(f(x)) = -6 + 2x.

The composition g[f(x)] is therefore -6 + 2x.

x3-10oo Dimensions ft each S.

The dimensions of Carl's square swimming pool, given that its volume is 1000 cubic feet, are approximately 10 feet by 10 feet by 10 feet.

Carl's swimming pool is a cube since all sides are equal. The volume of a cube is calculated by cubing one side (s^3). In this case, knowing that the volume is 1000 cubed feet, we can find the side length by taking the cube root of the volume. The cube root of 1000 is approximately 10 feet. Hence, the dimensions of Carl's swimming pool are 10 feet by 10 feet by 10 feet.

Let’s look at the first table. Set up the rule: y=kx You want to replace the variables with the numbers in the chart. Let’s do 11=k21. Since y is smaller than x we would most likely use a fraction or decimal. Now what we want to do is divide 11 by 21. This should give you the result of 0.5238095238 or ≈0.52 so the rule is y=0.52x.

Now let’s look at the second chart. Let’s do 1=k4. Same thing, divide 1 by 4 which will give you the result of 0.25. The rule of this table is y=0.25x.

These equations capture the linear relationships observed in the tables, allowing you to predict the value of y for any given value of x within these patterns.

In Table 1, you can observe that as the value of x decreases by 1, the value of y also decreases by 1. This suggests a linear relationship between x and y, where y is a function of x. The equation that describes this relationship is:

[tex]\[ y = x - 10 \][/tex]

In Table 2, there is a similar linear relationship between x and y. As x decreases, y also decreases, and the change in y is consistent. The equation for this relationship is:

[tex]\[ y = \frac{x}{4} + 5 \][/tex]

In both equations, the slope is -1 in the first table and 1/4 in the second table, indicating that for each unit change in x, there is a corresponding change in y. The y-intercepts in these equations are -10 and 5, respectively, representing the values of y when x is 0.

These equations capture the linear relationships observed in the tables, allowing you to predict the value of y for any given value of x within these patterns.

Step-by-step explanation:

GIVEN: Charlie biked [tex]15[/tex] minutes home from school and then walked [tex]12[/tex] minutes to the pizza place near his house. This trip was [tex]3.6[/tex] miles in total. His rate on his bike is [tex]3[/tex] miles per hour less than [tex]5[/tex] times his walking rate. In miles per hour.

TO FIND: Charlie’s speed as he walks and his speed as he bikes.

SOLUTION:

Let speed of charlie when he walks be [tex]x\text{ mph}[/tex]

Then speed of charlie as he biked [tex]=5x-3\text{ mph}[/tex]

Total length of trip [tex]=3.6\text{ miles}[/tex]

Total time taken[tex]=27\text{ minutes}=\frac{27}{60}\text{ hour}=\frac{9}{20}\text{hour}[/tex]

Now,

[tex]\text{Distance}=\text{speed}\times\text{time}[/tex]

distance traveled on bike [tex]=(5x-3)\times\frac{15}{60}=\frac{(5x-3)}{4}[/tex]

distance traveled by walking [tex]=x\times\frac{12}{60}=\frac{x}{5}[/tex]

As, [tex]\frac{(5x-3)}{4}+\frac{x}{5}=3.6[/tex]

     [tex]\frac{29x-15}{20}=3.6\implies 29x=87[/tex]

  [tex]\implies x=3\text{ mph}[/tex]

Speed of Charlie on bike [tex]=5x-3=12\text{ mph}[/tex]

Hence speed of charlie on bike and by walking is 12mph and 3mph respectively

Final answer:

There are 720 different permutations for filling the three positions (president, vice president, and secretary) among ten students on the student council.

Explanation:

The question asks for the number of different permutations there are for three positions (president, vice president, and secretary) among ten students on the student council.

This is a classic permutation problem in which order matters.

To calculate this, we can use the formula for permutations of 'n' items taken 'r' at a time, which is denoted as nPr and calculated as

n! / (n-r)!

where

'!' denotes factorial.

For this case, with ten students (n=10), and selecting three positions (r=3), the calculation would be:

10! / (10-3)! = 10! / 7! = 10 x 9 x 8 = 720.

Therefore, there are 720 different permutations available for the three positions on the student council.

Answer:

see the explanation

Step-by-step explanation:

we know that

The perimeter of rectangle is given by the formula

[tex]P=2(L+W)[/tex]

where

L is the length

W is the width

In this problem we have

[tex]P=322\ yd[/tex]

substitute

[tex]322=2(L+W)[/tex]

simplify

[tex]L+W=161\ yd[/tex]

so

The side lengths of the rectangle could be any pair of values whose sum must equal 161 yards

see the attached figure to better understand the problem

With the given height approximate the length of the rectangle

[tex]L=144\ ft[/tex]

Convert to yards

[tex]1\ yd=3\ ft[/tex]

so

[tex]144\ ft=144/3=48\ yd[/tex]

Find the width

[tex]48+W=161\\W=161-48\\W=113\ yd[/tex]

therefore

The side lengths of the rectangle could be 48 yd by 113 yd

2 possible solutions.

When width is 4 cm, length is 20 cm; When width is 20 cm, length is 4 cm

Step-by-step explanation:

Perimeter of the rectangle = 2(length + width)

48 = 2(length + x)

24 = length + x

⇒ Length = 24 - x

Area of the rectangle = length × width

80 = x (24 - x)

80 = 24x - x²

x² - 24x + 80 = 0

x² - 20x - 4x + 80 = 0

x(x - 20) - 4(x - 20) = 0

(x - 4)(x - 20) = 0

⇒ x = 4, 20

24 - x = 20, 4

So there are two possible answers.

When width is 4 cm, length is 20 cm

When width is 20 cm, length is 4 cm

The probability that both parts are defective is 6/55

Step-by-step explanation:

Defective parts = 4

Total parts = 11

Probability of getting a defective part = 4/11

Probability of getting defective part 2nd time = 3/10

Total probability of getting defective part both the times = (4/11) (3/10)

The number of bacteria on your phone after 4 hours is 81,000.

To calculate the number of bacteria on your phone after 4 hours using the exponential function f(x) = 1,000 * 3^x, we can substitute x with 4. So the equation becomes f(4) = 1,000 * 3^4.

Calculating this, we get f(4) = 1,000 * 81 = 81,000.
